Feasibility Study on Replacement of SHELL Diala Oil by Kelamayi EHV Transformer Oil

According to ASTM and DIN international standard and other equivalent GB standards, we finished a lot of experiments on physical chemical properties and electric performance of EHV transformer oil. Based on the experiments data, Kelamayi EHV Transformer Oils are compared with SHELL Diala oil. Domestic Kelamayi oils, which typed KI50AX and KI50GX are blended with SHELL Diala oil in different ratios to carry out mixed oils experiments. Research results show that Kelamayi EHV Transformer Oils which named KI50AX and KI50GX are superior to SHELL Diala oil in general properties.
